How to solve it by wolfram mathematica:
The fraction 49/98 is a curious fraction, as an inexperienced
mathematician in attempting to simplify it may incorrectly believe
that 49/98 = 4/8, which is correct, is obtained by cancelling the
9s.
We shall consider fractions like, 30/50 = 3/5, to be trivial
examples.
There are exactly four non-trivial examples of this type of
fraction, less than one in value, and containing two digits in the
numerator and denominator.
You have to identify these four fractions.
(This is "almost" Problem 33 from Euler project, with only the requirement modified).
Use wolffrom mathematics and c, n, d as natural digit between 1 to 9 for given conditions and make four possible equation then solving all in given conditions.then use c, d, n for getting desire solution.
